Vicki, this is Jeff from Domino's. I can answer a few of your questions about the Big Rig Rake.

The head of the rake is made of durable plastic and it has wheels on it so as to not scratch the roof of trailers.

It's not very useful for ice removal. We've used it to remove up to 10" of snow however.

The holes in the fiberglass tubes wear out quickly, however when I mentioned the weak point (the elbow that allows it to scrape the roof), the company took note and said they would pass it along to the development team.

When I expressed that the holes were wearing out, they quickly sent out two replacment poles free of charge. I'm not sure how often they would do this but thought it was worth mentioning.

If they somehow reinforce these weak points or construct the tubes out of Aluminum, this could last years I'm sure.

I emailed and was called the very next business day so I'm not sure why they haven't responded to you.
